HEATING-CABINET.

To all whom it may concern Be it known that we, EDWARD R. FENDER and ()rnxnmn L. YOUNT, citizens of the United States, residing at Chattanooga, in the county of Comanche, State of Oklahoma, have invented certain new and useful Improvements in Heating-Cabinets; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to new and useful improvements in heating cabirfets, and more especially to that class of cabinets for use in heating bread dough and the like to cause it to rise and the object of our invention is to provide a cabinet of the above described type in which the heat is furnished by means of an ordinary oil lamp.

A further object of our invention is to provide a cabinet having double walls, the inner walls being spaced from the outer walls to form air circulating passages by means of which the products of combustion from the lamp pass out of the cabinet without coming in contact with the food contained therein. And a still further object of our invention is to provide a novel form of means for securing the various walls together in such a manner that the cabinet may be readily put together, whereby the same may be shipped in a comparatively small space.

With these and other objects in view, our invention will be more fully described, illustrated in the drawings which show a preferred embodiment of the cabinet and then specifically pointed out in the claim which is attached to and forms a part of this application.

In. the accompanying drawings, Figure 1 is a front elevation of our improved cabinet. Fig. 2 is a top plan View. Fig. 3 is a section through the line 4-4 of Fig. 1. Fig. 4: is a vertical section through the cabinet.

Referring more specifically to the drawings in which similar reference numerals designate corresponding parts throughout,

our improved cabinet will be seen to consist primarily of an outer casing which as a whole is designated by the numeral 1 and an inner casing designated by the numeral 2. We prefer to construct the cabinet wholly of sheet metal, and as shown it con- Specification of Letters Patent.

sists of a base 3, a top 1, side walls 5 and 6, a back wall 7 and a front wall 8. The free edges of the back wall are bent to form rolls 9. as are also the free edges of the sides of the front wall and the side edges of the side walls 5 and 6 are bent to form rolls 10 so positioned as to telescope inside the rolls 9 whereby the front, back and side members are secured to each other without the use of bolts, rivets or other customary securing means. The base 3 is substantially rectangular in shape having rounded corners as at 11 to correspond in shape to the rolls above described, and having its edges bent up to form flanges 12 which bear against the outer faces of the side, front and back walls, whereby the said walls are maintained in proper .position with respect to the base. The top of the casing as shown is formed from a substantially rectangular shaped sheet of metal casing. The front and back edges of the top of the casing are bent downwardly to form flanges 15 which bear against the outer faces of the front and back walls of the casing. As a means for securing this outer casing together the rounded corners of the top and bottom thereof are each provided with a perforation 16 and bolts 17, one at each corner are passed through these perforations and through the rolls and throu h suitable feet 18 and secured in place fiy means of nuts 19. As shown the top of the casing is provided with a plurality of perforations 20 and covering these and spaced apart therefrom is a baille member 21 which is secured to the top of the casing by means of suitable bolts 29. The ends of this bafiie member are bent to form the rolls 23 by means of which said member is held in its spaced apart position with respect to the casing as best shown in Fig. 1 of the drawings.

As shown in the drawings the inner casing is open at the front and secured within the upper part of the outer casing in such a manner that its walls are spaced apart from the walls of the latter to form surrounding passages for air circulation. The back wall 24 of this inner casing is bent at its side edges to form rolls 25 which telescope in similar rolls 26 formed in the rear edges of the side walls 27 and 28, the front edges of cular plate 34 being provided for covering which extend forwardly to the front wall ofthe outer casing and are then bent to one side to form lateral flanges 29 which as shown, bear against the inner face of the front wall of the outer casing, said flanges terminating adjacent the rolls 10 of the side walls. The lower edges of the side and back walls of the inner casing are bent inwardly to form supporting flanges 31 upon which is seated the base 32 of the inner casing, which as shown is provided centrally with a relatively large circular aperture 32 adapted to receive a basin 33 for holding water, a cirthis aperture when the basin is not in use. The top of the inner casing consists of a sheet metal plate 35 having at its sides and back downwardly bent flange members 36 which engage against the outer faces of the side and back walls of the inner casing when the top is in place. Each of the side walls of the inner casing is provided with a plurality of spaced apart, inwardly extending, transverse ribs 37 adapted to support a. plurality of grate members 38 in adjusted position. This inner casing is secured in place in the upper portion of the outer casing by means of a plurality of bolts 39 which are passed through the side wallsof both the inner and outer casing. The lower portion of each of the side walls of the outer casing is provided with a plurality of spaced apart U-shaped clefts forming a plurality of apertures &0 which as shown permit free passage of air into the outer casing.

In operation the dough to be raised, contained in suitable receptacles, is placed upon the shelves in the inner casing and the lamp or other suitable-heating device is placed within the lower portion of the outer casing 1 when the doors are closed. As will be readi ily understood the heat from the lamp will i soon raise the temperature in the cabinet to j the required degree, air circulation being provided by the apertures 4:0 as previously described. All smoke and fumes from the j burning lamp pass upwardly between the i side and back walls of the inner casing and the side and back walls of the outer casing and out through the apertures on top of the outer casing.

In order to keep the dough moist while being raised and thus prevent the formation of a crust thereon the plate 34 may be removed from the aperture 32 and the basin 33 partially filled with water may be seated. in said aperture and it will be readily understood that the vapor generated by the heating of the water will serve to maintain the dough in a slightly moistened condition.

From the foregoing description it will be apparent that our cabinet is simple and economical in construction and easily taken apart, and is therefore capable of being packed in small space for shipment.

It will be understood that the above described cabinet may be used as an oven in connection with oil and gas stoves and the like, without in the slightest degree departing from the spirit of our invention.

\Vhat we claim is A heating cabinet comprising an outer casing and an inner casing supported in the outer casing with its walls spaced from those of the outer casing and having its front wall provided with an opening, the adjacent edges of the rear and side walls of the inner casing being united by an outwardly disposed roll joint engaging the adjacent inner faces of the walls of the outer casing and maintaining the adjacent portion of the inner casing in spaced relation to the side and rear walls of the outer casing, a door hinged to the outer casing for closing the opening in the front wall of the inner casing, and heat generating means in said outer casing below the inner casing.

In testimony whereof, we affix our signatures, in presence of two witnesses.
